Context

Recently, Vikram-1, India’s first privately developed orbital-class launch vehicle, was declared ready for its maiden launch, marking a major milestone in India’s private space sector.

About Vikram-1

  1. It is developed by Skyroot Aerospace and is a four-stage launch vehicle, with the first three stages powered by solid-fuel motors and the fourth stage using hypergolic liquid propulsion for precise orbital insertion.
  2. The fourth stage is powered by a cluster of four Raman engines that use Monomethylhydrazine (MMH) as fuel and Nitrogen Tetroxide (NTO) as the oxidiser. Being hypergolic, these propellants ignite automatically on contact, ensuring reliable engine ignition.
  3. The launch vehicle features an all-carbon composite structure and incorporates indigenously developed 3D-printed engines along with high-thrust solid rocket motors.
  4. It can carry payloads of up to 350 kg to Low Earth Orbit (LEO) and 260 kg to Sun-Synchronous Orbit (SSO).
  5. Designed for the small-satellite launch market, it is capable of deploying multiple satellites in a single mission.
  6. Its design emphasises simplicity, reliability, and rapid launch readiness, enabling launch within 24 hours from suitable launch locations.
  7. The rocket incorporates ultra-low-shock pneumatic separation systems and advanced avionics to ensure accurate guidance, navigation, and mission control.

The launch vehicle is designed to support the growing small-satellite launch market while expanding private sector participation in India’s space programme.
